M Series Connectors
Are lightweight triplestart ratchet coupling type connectors designed for avionics, aerospace, Harsh Environment Connectors, security, motorsport and heavy duty applications.
While GX12 and GX16 connectors share the same circular aviation design DNA, choosing the wrong one can lead to installation failures or power overloads. The core difference lies in their shell size (12mm vs. 16mm), which directly impacts their pin capacity and current rating. In this guide, we break down the critical technical distinctions between the GX12 and GX16 series—covering pinouts, voltage, and application scenarios—to help you specify the correct component for your project.

Quick Look: GX12 vs. GX16 Specification Comparison
The connectors are both round in shape and have a set of pins or sockets that can be connected to other devices. They are also commonly used in various electronic devices such as computers, televisions, and appliances. One notable similarity between the GX12 connector and GX16 connector is that they are both used to transmit signals. Specifically, they can transmit electrical, data, or power signals, depending on the particular device and application.
Difference Between GX12 and GX16 Connectors
1.Dimensions and Pinouts
There is a significant difference in physical footprint:
-
GX12: Approximately 12 mm in diameter. Ideally suited for compact devices where space is limited.
-
GX16: Approximately 16 mm in diameter. The larger shell allows for higher durability and easier handling in industrial settings.
This size difference also dictates electrical performance. The GX16 supports a higher rated voltage (400 V vs. 250 V) and doubles the current carrying capacity (10 A vs. 5 A) compared to the GX12.
2.Number of Pins
The number of GX12 pins
GX12 connectors are available in a variety of pin configurations, typically 2 to 8 pins.
The number of GX16 pins
GX16 connector has a higher pin count, typically 2 to 14 pins.The difference in the number of pins affects the type of signals the connector can carry and the devices it is compatible with.
3.Current-carrying Capacity
GX12: Due to their smaller size, GX12 connectors typically have a lower current carrying capacity than GX16 connectors. They are suitable for applications with moderate power requirements.
GX16: GX16 connectors are larger and have a higher current carrying capacity, making them more suitable for applications requiring higher power transmission.
4.Applications
GX12 connectors are often used in audio and video equipment, sensors, and small electronic devices. In computer peripherals, GX12 connectors are widely used to connect printers and external hard disks for data transfer.
GX16 connectors are widely used in aerospace, industrial machinery and high power electrical systems, mainly for transmitting data and power signals. In the consumer electronics space, GX16 connectors are extremely popular in custom mechanical keyboard cables (Aviator Cables) and DIY PC modding. They are also standard components in 3D printers and CNC routers for connecting stepper motors and hotends due to their secure locking mechanism. In addition, GX16 connectors are used in applications that require high voltage and current carrying capacity, such as communication systems, radar equipment and control panels in the aviation, aerospace and defense industries, as well as in industrial machinery, generators and electric vehicles.
5.Waterproof and Environmentally Friendly
Both GX12 and GX16 connectors are water and dust resistant. Waterproof rating is typically IP55. These models are suitable for outdoor and harsh environments. They are effective in establishing an electrical connection between two devices in wet environments such as rain, humidity and pressurized water.
6.Compatibility
The GX12 and GX16 connectors are not compatible with each other as far as pin arrangement and design are concerned. They have different pinouts and dimensions and are therefore not directly interchangeable.

Conclusion
In conclusion, the GX12 and GX16 connectors are circular connectors that differ in size, pin layout and application. GX12 connectors are suitable for small devices and low power applications. The GX16 connectors are for high power applications and complex systems. When selecting a connector, it is important to consider voltage and current carrying capacity, as well as size and pinout. By understanding the differences between GX12 and GX16 connectors, you can choose the right connector from Renhotec for your application and ensure a reliable and secure connection.
FAQ: GX12 vs GX16
Q: Are GX12 and GX16 connectors interchangeable?
A: No, they are not. GX12 requires a 12mm mounting hole, while GX16 requires a 16mm hole. Their threads cannot mate with each other.
Q: Which connector handles more power?
A: The GX16 is the stronger option, handling up to 10A and 400V, whereas the GX12 is limited to 5A and 250V.
Q: What does the “GX” stand for?
A: “GX” refers to the series type of circular aviation connectors, often known as “Aviator Connectors,” widely used for their screw-locking nut that prevents accidental disconnection.
Do you have smaller size thsn GX12?
Hi John, thank you for your valuable comment!
GX12 is currently the smallest size available in our GX series. For more compact options, we recommend our M8 or M5 series connectors. Feel free to share your application requirements — we’d be happy to help you find the best fit.
